The story in Mini Ninjas is one of magic, heroism and the importance of fellowship. Hiro is a young Ninja and the last person that anyone would expect to be asked to save the world. Yet that is exactly what happens when the Evil Samurai Warlord hatches a fiendish plan to raise an army bent on world domination. Hiro must lead his small band of Mini Ninjas on an exciting journey through a disintegrating world, battle the magical hordes of twisted Samurai, and eventually confront the Warlord in his Fortress of Doom.
